1. By studying the discrete fourier transform properties of the band - limited digital signal , the authors introduce alternating projection neural networks into the paper , expand apnn ' s application scope from real field to complex field , and present several important conclusions on apnn . analyzing and discussing network ' s tolerance to noise , convergence rate and the spectral leakage problem of the truncated signal expected to be extrapolated by using these conclusions , the paper presents an extrapolation algorithm for band - limited signals based on alternating projection neural networks . a lot of simulation experiments show that the algorithm is effective . in addition , the algorithm is also effective to spectrum extrapolation . owing to adopting network structure , the algorithm is prone to parallel computation and vlsi design , and consequently can satisfy real time military processing needs
   本文通過對頻帶受限數(shù)字信號的離散傅立葉變換特性的研究，引進(jìn)了交替投影神經(jīng)網(wǎng)絡(luò)，并將其應(yīng)用范圍從實數(shù)域拓廣到復(fù)數(shù)域，且給出了在復(fù)數(shù)域仍然成立的若干結(jié)論.運用這些結(jié)論，在對網(wǎng)絡(luò)噪聲抑制、網(wǎng)絡(luò)收斂速度及待外推信號因截斷而造成頻譜嚴(yán)重外泄問題的分析與討論的基礎(chǔ)上，提出了一種基于交替投影神經(jīng)網(wǎng)絡(luò)的外推算法.仿真實驗表明該方法是行之有效的.另外，該算法對頻譜外推同樣適用；由于它采用全互連神經(jīng)網(wǎng)絡(luò)結(jié)構(gòu)，易于并行計算和vlsi實現(xiàn)，從而可滿足軍事上實時處理的需要
2. It's difficult to find truncated signal in a sentence. 用truncated signal造句挺難的
